[Evolution] URL's do not work anymore

[Cecil Westerhof <CecilWesterhof xs4all nl>]

I updated from Evolution 1.4 to 2.0. There where some problems with
signatures. They where not converted and the config file was still
pointing to ~/evolution instead of ~/.evolution, but that is solved now.
What does not work are URL's. In 1.4 if I clicked an URL, this was
opened in my webbrowser. This does not work anymore. I have to copy and
paste it.
What could be the problem here?
